Our assessment
Our assessment: The evidence for calcium is clear — it is essential for bone health, but it is not without risks. For most adults, getting calcium from food is preferable to supplements, as high-dose supplementation carries potential health concerns [NIH ODS]. You should aim for the RDA through diet first, and only consider a supplement if you cannot meet that goal.
How it works
Calcium is a mineral that acts as a key building block for your skeleton. It supports bone mineralization, meaning it helps deposit minerals into bone tissue to maintain density and strength. Calcium also plays a role in neuromuscular relaxation, helping your muscles relax and your nerves signal properly after they fire [NIH ODS].
Safety profile
FDA received 592,059 total adverse event reports for this supplement category [FDA data]. Safety data shows that high calcium intakes might increase the risk of heart disease and prostate cancer. Very high levels of calcium in the blood and urine can cause poor muscle tone, poor kidney function, low phosphate levels, constipation, nausea, weight loss, extreme tiredness, frequent need to urinate, abnormal heart rhythms, and a high risk of death from heart disease [NIH ODS]. Calcium can also reduce the absorption of several medications, including bisphosphonates, tetracycline antibiotics, fluoroquinolone antibiotics, levothyroxine, and phenytoin [NIH ODS].
Our recommendation
Our recommendation: Do not take a calcium supplement unless you have confirmed you cannot get enough from food. If you do supplement, keep the dose moderate and take it with food. Monitor for side effects like constipation or nausea. Always discuss with your doctor if you take any of the listed medications, as timing and dosing adjustments may be necessary [NIH ODS].
